From: Thomas Antoine <t.antoine@xxxxxxxxxxxx>
Add the node for the max77759 fuel gauge as a slave of the i2c.
The todo is still applicable given there are other slaves on the
bus (pca9468, other max77759 functions and the max20339 OVP).
The fuel gauge has been tested and seems to give coherent results.
Manual activation of the charger via i2cset shows that the sign of
the current does indicate charging/discharging status.
